BA3121 Features

In normal mode, the BA3121 continuously monitors the discharge current by sensing the voltage of CS pin. If the voltage of CS pin exceeds the overcurrent protection voltage (V OIP) beyond the overcurrent delay time (TOI) period, the overcurrent protection circuit operates and discharging is inhibited by the turning-off of the discharge control MOSFET M1. The overcurrent condition returns to the normal mode when the load is released and the impedance between the BATT+ and BATT- terminals is 20M? or higher. The BA3121 is provided with the two overcurrent detection levels (0.2V and 1V) and the two overcurrent delay time (TOI1 and TOI2) corresponding to each overcurrent detection level.
